GeForce GTX 950M vs Radeon HD 5570

Intro

The GeForce GTX 950M comes with a core clock frequency of 914 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon HD 5570, which comes with core clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 RAM. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570 43 Watts
GeForce GTX 950M 55 Watts
Difference: 12 Watts (28%)

Memory Bandwidth

In theory, the GeForce GTX 950M should be 11% quicker than the Radeon HD 5570 in general, because of its greater data rate. (explain)

GeForce GTX 950M 32000 MB/sec
Radeon HD 5570 28800 MB/sec
Difference: 3200 (11%)

Texel Rate

The GeForce GTX 950M will be quite a bit (more or less 181%) better at anisotropic filtering than the Radeon HD 5570. (explain)

GeForce GTX 950M 36560 Mtexels/sec
Radeon HD 5570 13000 Mtexels/sec
Difference: 23560 (181%)

Pixel Rate

The GeForce GTX 950M is much (more or less 181%) better at AA than the Radeon HD 5570, and will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 950M 14624 Mpixels/sec
Radeon HD 5570 5200 Mpixels/sec
Difference: 9424 (181%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
